dev-manual: Updated section on how checksums are dealt with

In the "Fetching Code" section, some loose description of how the
build system reacts to the two checksums in a recipe existed.
Robert asked some questions about how the behavior would be if
just a single, correct checksum existed and if the two existed but
only one proved correct.  Turns out, if you supply a single one then
the build will not throw an error or warning.  If you supply two
but one is incorrect, then the build will throw an error or
warning.  I updated the text to be technically correct without
going into huge details.

If no <filename>SRC_URI</filename> checksums are specified
when you attempt to build the recipe, the build will produce
an error for each missing checksum.
when you attempt to build the recipe, or you provide an
incorrect checksum, the build will produce an error for each
missing or incorrect checksum.
As part of the error message, the build system provides
the checksum string corresponding to the fetched file.
Once you have the correct checksums, you can copy and paste
